PRINT A BATTERY : PRINTABLE BATTERY

1. Before I get into the meaning lemme tell you that this is again astonishing discovery.you can take a print out of something as shown in figure and use it as a battery..I mean as a source of power.....read ahead to find out.

2. A new type of low-power battery that does not require a case and is thin enough to be printed on paper is all set to venture on ur laps and desktop tables.The power source relies on an undisclosed mixture of chemicals to produce 20 milliamp-hours at a terminal voltage of 1.5 volts for every square centimetre that is printed. The battery material is roughly 0.5 millimetres thick and would, if mass-produced, cost just a few cents per square inch, according to Israeli-based company Power Paper.
3. The subject battery has been developed by a team led by Prof. Dr. Reinhard Baumann of the Fraunhofer Research Institution for Electronic Nano Systems.

4. As this is a printable battery so the characteristics of this battery differ significantly from those of conventional batteries. As the name suggest it must have very less weight.It weighs less than one gram on the scales, is not even one millimeter thick and can therefore be integrated into bank cards.It's voltage is 1.5 V, which is general.The battery weighs less than one gram on the scales, is not even one millimeter thick and can therefore be integrated into bank cards, for example. The battery contains no mercury and is in this respect environmentally friendly. Its voltage is 1.5 V, which lies within the normal range. By placing several batteries in a row, voltages of 3 V, 4.5 V and 6 V can also be achieved. 

5. It is composed of different layers: a zinc anode and a manganese cathode, among others. Zinc and manganese react with one another and produce electricity. However, the anode and the cathode layer dissipate gradually during this chemical process. Therefore, the battery is suitable for applications which have a limited life span or a limited power requirement, for instance greeting cards

6. The new battery consists of three different layers. It has conventional zinc manganese-dioxide components as anode and cathode. Sandwiched in between, the cell's chemical power source remains a closely guarded secret.

7. Paper Power claims the material is non-toxic and non-corrosive, making the battery safe to use without casing."Technically it will work like any other battery, but you can cut the battery into any size and shape for your product."
